July Temps and Dew Points

Posted: 04 Jul 2017 05:45 AM

The muggy conditions that most Iowans equate with July was present on Monday for most of the state. Dew point temperatures reached the lower 70s for about the southern 2/3rd s of the state. The featured chart looks at the combination of average dew point at a given temperature along with the resulting dew point. The relative humidity plot shows a rather smooth relationship as once temperatures start reaching the mid 70s, our relative humidities start to drop. We should be thankful for this relationship was it allows some level of suitability to our weather as temperatures warm mostly independently of dew point. The general flat portion of the relative humidity curve below the mid 70s are indicative of the common near saturated condition that supports warm over night temperatures.

Good = 5
Bad = 0
